[Virus] Infecté par win32 trojan-gen.{Delphi}

Bonjour,

Mon pc sous vista est infecté par win32 trojan-gen.{Delphi} et avast n'arrive pas à le supprimer. Il est localisé dans C:\Windows\Installer. Le programme c'est que je n'arrive pas à voir ce dosser, même en affichant les dossiers cachés. Que faire?

Je vous remercie par avance et vous précise que je n'ai actuellement pas internet sur mon pc infecté donc je ne pourrai pas faire de scan en ligne.

Voici le log hijackthis :
